18gramsdark chocolateor 1 to 1 1/2 tbsp chocolate chips
Instructions
Add all of the ingredients except for the chocolate to a Ninja Creami pint container. Blend with an immersion blender until smooth.
Cover the pint and freeze on a level surface in the freezer for 24 hours.
After the pint is thoroughly frozen, install it in your Ninja Creami machine per manufacturer's instructions for you model. Spin on "Lite Ice Cream."
While the ice cream is spinning, add your dark chocolate to a microwave-safe dish. Microwave in 30-second increments until melted, stirring in between.
When the first spin is done, check the texture of the ice cream. If it is at least 50% of the way to your ideal texture (so looks like ice cream, but may not be perfectly smooth yet) procede with the next step. If your ice cream is still powdery and not yet looking close to edible, then do one spin cycle with the "Re-Spin" button.
When the ice cream is decently smooth and the chocolate chips are melted, work quickly to make a well in the center of the ice cream that goes down deep to the bottom. Scrape the melted chocolate into the well, then quickly place the pint container back into your machine. Press the "Mix In" button.
Your mint chip protein ice cream is now ready to enjoy!
Notes
For some brands of mint extract, 1/4 tsp might be too high and give an unpleasant aftertaste. If you notice that in your ice cream, you can dial back to 1/8 tsp. 1/8 tsp may not be strong enough for other brands, so it's really going to depend on what you buy. I do not recommend going higher than 1/4 tsp, and make sure to measure carefully. Mint extract isn't like vanilla where a little extra can be tasty--too much can ruin the ice cream!
